摘要：

Oolongtheanins, catechin dimers derived from oolong tea leaves, were isolated by Hashimoto et al. in 1988. Later, Tanaka et al. revised the oolongtheanin structure. In this study, it was clarified that oolongtheanins in organic solvent like acetone or methanol have the structures proposed by Tanaka et al. Based on the hydrogen/deuterium exchange reaction in aqueous solution, it was suggested that they exist as an equilibrium mixture of the structures proposed by Hashimoto and Tanaka.
